Mine has always set low on the driver's side of the grille. It used a bracket I made about 50 years ago...attaches between the bumper and the bumper support and is held in place by the bumper bolt. Very easy to make, but use at least 3/16 inch thick metal or the wind will bend it. I've also seen these mounted right in front of the bumper (in the middle---there is a hole there already) so the plate doesn't catch too much wind. The wind isn't a problem if you just putter around town, though.
